Cloud Computing: Architectural and Policy Implications

Cloud computing has emerged as perhaps the hottest development in information technology. Despite all of the attention it has garnered, existing analyses focus almost exclusively on the issues surrounding data privacy without exploring cloud computing’s architectural and policy implications. This Article offers an initial exploratory analysis in that direction. It begins by introducing key cloud computing concepts, such as service oriented architectures, thin clients, and virtualization, and discusses the leading delivery models and deployment strategies being pursued by cloud computing providers. It then analyzes the economics of cloud computing in terms of reducing costs, transforming capital expenditures into operating expenditures, aggregating demand, increasing reliability, and reducing latency. It then discusses the architectural implications of cloud computing for access networking (focusing on bandwidth, reliability, quality of service, and ubiquity) and data center interconnectivity (focusing on bandwidth, reliability, security and privacy, control over routing policies, standardization, and metering and payment). It closes by offering a few observations on the impact of cloud computing on the industry structure for data centers, server-related technologies, router-based technologies, and access networks, as well as its implications for regulation.     

An analysis of prediction error for new prime-time television programmes: a comparative study between the USA and Korea

This study investigates possible factors in prediction error for audience share for new prime-time television programmes in the USA and Korea. While previous studies have focused on the factors affecting the size of a programme's actual audience, little attention has been paid to the accuracy of audience share prediction. A total of 193 new prime-time TV programmes from 1994 to 1997 for the USA and from 1998 to 2001 for Korea were examined. Advertising industry forecasters' predicted audience share, and actual share data were accumulated from Broadcasting & Cable and Weekly Nielsen Reports. Findings show that the ‘Programme Type’, ‘Returning Lead-Ins’ and ‘Returning Lead-Outs’ worked as significant factors for estimating error in audience share in the USA, and ‘Programme Type’ and ‘Programme Length’ played major roles in forecasting error in Korea. The degrees of relationship with forecasting error are consistent with previous studies' findings. Similarities and dissimilarities in prediction error in both countries were found and are discussed in this study.     

PARCHING THE LAND?: THE CHETTIARS IN BURMA

In the history of Burma's economy, few groups have been as vilified as the Chettiars. A community of Indian moneylenders, the Chettiars were crucial agents in transforming Burma into the rice bowl of Asia. Following the global depression of the 1930s, Burmese agriculture became severely distressed and wide-scale loan default saw the transfer of much of Burma's cultivatable land to the Chettiars, who were demonised and made scapegoats for the vices of colonialism. The paper draws on the 'information-theoretic revolution' in economics to reappraise the role of the Chettiars in Burma. We conclude the Chettiars merit history's better judgement.     

SHORT SELLING AND MISPRICINGS WHEN FUNDAMENTALS ARE KNOWN: EVIDENCE FROM NYSE‐TRADED CLOSED‐END FUNDS

The larger a closed‐end fund's premium over its portfolio value, the more intensely it is sold short. This behavior should reduce mispricings. However, short selling affects neither the observed rate at which premia revert to fundamental values nor the rate of return on a fund's shares. This apparent contradiction can be explained as follows: short selling does reduce prices, but the effect is impounded into prices by the time short positions are tabulated by the NYSE each month. Consequently, the monthly short selling data do not predict future price movements.     

The traditional marketplace: serious leisure and recommending authentic travel

ABSTRACT

Services reliant on revenue generated from tourism are often beholden to how authentic visitors perceive their offering to be. From a managerial perspective, this is exacerbated when they serve a dual-purpose, as both actively ingrained in local culture and showcased international tourist attractions. As such, this study contributes to Kolar and ?abkar’s (2010) consumer-based model of authenticity by assessing the relationships between serious leisure, object-based and existential authenticity, and visitor word-of-mouth (WOM) recommendations in Iranian cultural tourism. Utilising partial least-squares structural equation modelling, and drawing upon responses from 615 visitors to the Tabriz Grand Bazaar, it thus extends the model’s applicability to the developing Middle Eastern context. The results extend extant research by emphasising the importance of object-based authenticity, as opposed to existential authenticity, in stimulating positive visitor WOM recommendations. Consequently, this study advances the prevailing understanding of the role of authenticity in stimulating positive behavioural intentions by highlighting how destinations can stimulate visitor recommendations.     

Budget negotiations in multi-period settings

Budgets are typically set through a negotiation process that is repeated in successive periods, often between the same superior and subordinate. Despite this, little is known about budget negotiations in multi-period settings. Temporal interdependence is a fundamental aspect of budget negotiations in multi-period settings, and it refers to the fact that in multi-period budget settings, superiors’ (subordinates’) decisions and actions in one period can be influenced by subordinates’ (superiors’) decisions and actions in earlier periods and, in turn, can influence subordinates’ (superiors’) decisions and actions in later periods. We report the results of an experiment that addresses two issues related to temporal interdependence.
